Key takeaways
- Common NTAG chips hold more than enough for a web link.
- Write a link you control, so you can change the destination without touching the tag.
- Lock tags after writing so nobody can overwrite them.
- Metal blocks ordinary tags — use on-metal tags there.
An NFC tag is a small, inexpensive chip that opens something on a customer's phone when they tap it. Getting it right comes down to a few practical choices.
Choosing tags
- Common chips such as NTAG213, 215 and 216 hold more than enough for a web link.
- Pick the form that suits the spot: cards, stickers, stands or plates.
- For metal surfaces, use tags made for metal — ordinary tags often won't read on metal.
What to write
Write a short web link. Ideally, make it a link you control that forwards to the real destination; then you can change where the tag goes later without rewriting or replacing it.
Lock it
An unlocked tag can be rewritten by anyone with an app. After writing and testing, lock the tag so its content can't be changed.
Place and test
- 1Mark the tap spot clearly with an icon and a short line such as “Tap to review us on Google”.
- 2Put it where customers naturally hold their phone.
- 3Test on at least one Android phone and one iPhone, in place.
- 4Add a QR code nearby for phones without NFC.
Good uses
- Google review cards and table stands.
- Menus on tables.
- Digital business cards.
- Product details on shelves.
- Social profiles and WhatsApp chat.
Frequently asked questions
- Can I program NFC tags myself?
- Yes. Free phone apps can write a link to a blank tag. Test it on several phones, then lock it.
uTapiT tags come programmed, locked and tested, pointing to a link you can repoint from your dashboard.
